=head1 NAME
check_emc_clariion.pl - Checks EMC SAN devices for NAGIOS.
=head1 SYNOPSIS
check_emc_clariion.pl -h | --help
check_emc_clariion.pl -H <host> -t <checktype>
check_emc_clariion.pl -H <host> -u <user> -p <password> -t <checktype>
=head1 DESCRIPTION
B<check_emc_clariion.pl> receives the data from the emc devices via Navicli or Naviseccli if user and password are provided.
=head1 OPTIONS
=over 8
=item B<-h>
Display this helpmessage.
=item B<-H>
The hostname or ipaddress of the emc storage processor device.
=item B<-u>
The user used to connect to the emc storage processor device with Naviseccli.
You must use this option with -password !
=item B<-p>
The password of the user used to connect to the emc storage processor device with Naviseccli.
=item B<-t>
The check type to execute:
=back
=head2 TYPES
the following checks are currently available
sp - check the status of the storage processors
disk - check the status of the physical disks attached in the DAE`s
cache - check the status of the read and write cache
faults - Report the different faults on the array
portstate - check the status of the FC ports in the SP`s
hbastate - check the connection state of the specified node
=head3 TYPE OPTIONS
=head4 sp
=over 8
=item B<--sp>
The storageprocessor to check e.g. A or B
=back
=head4 portstate
=over 8
=item B<--sp>
The storageprocessor to check e.g. A or B
=item B<--port>
The port ID to check e.g. 0 or 1 or 0, 1, 2 or 3 for Clariion CX3-80
- if not specified, all ports are checked
=back
=head4 hbastate
=over 8
=item B<--node>
The node name to check out of navisphere
=item B<--paths>
The number of available FC Paths from the client to the SAN Infrastructure e.g. 2
